Extra Virgin Olive Oil Contains a very high concentration of Squalene, a very powerful antioxidant. It is also rich in vitamins A, D, and K, as well as vitamin E. It is an excellent moisturizer and fights off bacteria, which is perfect for acne prone skin.Sodium Hydroxide Originally discovered as a by-product of hardwood ash, sodium hydroxide is now manufactured to create a cleaner product. When sodium hydroxide and oil are mixed together a chemical reaction called saponification occurs. The end product is soap. If the recipe is properly calculated, no excess lye remains in the soap. In fact, T•L Bars are formulated to have an abundance of olive oil unsaponified, which makes them super moisturizing!
